After their successful nine-hour dive in January 1960 to the bottom of the Pacific Ocean’s Mariana Trench, Don Walsh and Jacques Piccard emerge from the bathyscaphe Trieste. Walsh and Piccard were the first to reach the trench’s lowest point, Challenger Deep, some 35,800 feet below the ocean surface. Piccard, who died in 2008, was posthumously awarded the Hubbard Medal, the National Geographic highest honor, at a ceremony in Washington, D.C., on June 14, 2012. (Photo: Thomas J. Abercrombie)

Only three men have ever reached the ocean’s deepest point. Capt. Don Walsh and the late Jacques Piccard in 1960 and earlier this year, James Cameron. On June 14th, 2012, National Geographic bestowed its highest honor, the Hubbard Medal, posthumously to Jacques Piccard for his record-breaking dive to the Mariana Trench with Don Walsh in the bathyscaphe Trieste to a depth of nearly seven miles. Many of his efforts greatly contributed to the fields of oceanography and conservation.

Piccard comes from a family of explorers. His father, Auguste, was a physicist and the first man to take a balloon into the stratosphere. In 1999, Jacques Piccard’s son, Bertrand Piccard, together with Brian Jones, completed the first ever nonstop circumnavigation of the globe in a balloon.

Presenting the Piccard family with the Medal was Don Walsh, who received the Hubbard Medal in 2010 and James Cameron, the last and only other man to reach this depth.

August 15, 2011: Our special guest is National Geographic Fellow and acclaimed chef, author, and speaker Barton Seaver, who seeks to restore our relationship with the ocean, the land, and with each other through dinner. His new book is For Cod and Country: Simple, Delicious, Sustainable Cooking. If you’re not hungry, you will be by the end of this show!

August 1, 2011: We visit National Geographic Headquarters in Washington, DC to meet the newest National Geographic “Explorer in Residence,” Dr. Enric Sala and his important work on the “Pristine Seas” program with expeditions to the last remaining pristine areas in the ocean. We also hear the incredible story of a humpback whale, rescued at the brink of death, that said “thank you” to its human rescuers. And we hear the tragic story of the loss of one of our colleagues in Cuba.

Earlier this year, World Resources Institute released its “Reefs at Risk Revisited Report” (featured on The Ocean Doctor Radio Show) which spelled out a rather grim future for coral reefs due to both local and global threats, should we fail to take action. One of the bright spots in its report was Australia’s Great Barrier Reef, which has fared better than many other reefs around the world and has in place strong protections and management practices. But even this massive and remote reef system isn’t immune from the impacts affecting coral reefs worldwide. In “A Fragile Empire” National Geographic Magazine (May 2011) writer Jennifer S. Holland explores the various factors that are threatening Australia’s monumental reef. From rising water temperatures, to bleaching, massive flooding and high levels of acidity, the reef is in danger of collapsing and the prospect for recovery is uncertain.

A warming climate is pushing corals against the upper limit of their thermal tolerance, evidenced by mass bleachings like the one in 1997-98. A 60-year decline in ocean phytoplankton — microscopic organisms that form the base of the food chain — may also be playing a role. Recent flooding in Australia washed enormous plumes of sediments and toxins far offshore to the reef tract. And now, thanks to increasing carbon dioxide levels in the atmosphere, the oceans are becoming more and more acidic as more of this atmospheric carbon dioxide dissolves in seawater. As the oceans become more acid, limiting the ability of organisms, like corals and shellfish, to build their limestone shells and skeletons.

They’re favorites among divers and fishermen, they’re teeming with life, and they’re heralded as a way to rebuild dwindling fish populations. They’re also controversial. With the breathtaking imagery of renowned National Geographic photographer David Doubilet, the February 2011 issue of National Geographic Magazine brings us deep into the heart of the artificial reefs found throughout our ocean waters.

November 8, 2010: In the oceans, Mother Nature continues to surprise and delight us with mesmerizing, jaw-dropping marine life that often wildly exceeds our imagination. Released at the completion of the decade-long Census of Marine Life, the? new book from National Geographic, Citizens of the Sea: Wondrous Creatures From the Census of Marine Life,? is not only rich with the captivating images you’d expect from the seasoned underwater photographers of National Geographic and the Census of Marine Life, but its delightful prose by author Dr. Nancy Knowlton — Sant Chair for Marine Science at the Smithsonian’s National Museum of Natural History and a scientific leader of the Census of Marine Life — brings these photographs to life in captivating vignettes that will playfully bend your brain with utterly amazing facts about these utterly amazing creatures, including the Bob Marley Worm and a fish with a head you (and it) can see right through. We visit with Dr. Knowlton at her office at Smithsonian and take a field trip to the Smithsonian’s latest and wildly popular exhibit, the “Hyperbolic Crochet Coral Reef.”

A Special ExpeditionCasts Presentation: Lessons from Ocean Explorers: Why Conservation Needs Exploration. Renowned ocean explorers and adventurers gathered at the Carnegie Institution for Science on March 7, 2009 to kick off the Blue Vision Summit, a project of the Blue Frontier Campaign. With stunning imagery and stories from the deep, this unique panel discusses the importance of ocean exploration, its future, and how exploration is vital to the advancement of the conservation of the oceans.

The ExpeditionCasts podcast is back! The series returns with the video version of the Ocean Doctor’s popular blog post, “Attacked by the Giant Squid’s Cousins.” (You can access the video version below.) That’s big news. But the GINORMOUS news is that ExpeditionCasts returns along with a new version of Google Earth. Version 5.0 of Google Earth allows you to explore the other 70 percent of the planet — the world’s oceans — and access stunning underwater video content from around the world.We have been privileged to be a contributor to this enormous, er, GINORMOUS project, and you’ll find five ExpeditionCasts videos among the others Google Earth 5.0. Look for them in Alaska’s Bering Sea and off the northwestern coast of Cuba.
